NOT_ALLOWED

Error message

You must provide the region_id to list payment providers

What it means

Thrown by GET /store/payment-providers when the required region_id filter is missing. Payment providers are scoped per region in Medusa, so listing them requires knowing which region to query. The route validates req.filterableFields.region_id and throws NOT_ALLOWED when absent.

Solutions

  1. Pass region_id as a query parameter: GET /store/payment-providers?region_id=re_...
  2. Derive the region_id from the current cart (cart.region_id) before calling the endpoint
  3. Ensure your region bootstrap logic (e.g. region cookie resolution) has run before fetching providers

Example fix

// before
const providers = await sdk.store.paymentProvider.list({}) // 400-ish: region_id required

// after
const providers = await sdk.store.paymentProvider.list({ region_id: cart.region_id })
Defensive patterns

Strategy: validation

Validate before calling

if (!regionId) throw new Error('Select a region first')
const providers = await sdk.store.paymentProvider.list({ region_id: regionId })

Type guard

const hasRegionId = (cart: Cart | null): cart is Cart & { region_id: string } =>
  !!cart?.region_id

Prevention

When it happens

Trigger: Calling GET /store/payment-providers without ?region_id=... in the query string.

Common situations: Frontend fetches payment providers before a cart/region is selected; region_id stored in local state is null/undefined and serialized as nothing; forgetting the query param after upgrading storefront code.
